How to tell what version of PCI Express slot your system has?

I have just bought Lenovo H50 90C1 desktop system. It has one PCI Express slot, unmarked (does not say 3.0). There is no name on the motherboard other than Lenovo, it is an internal cheap motherboard without any specs. Neither the manual nor the website, nor the sales know anything about which PCI Express version this slot is, 2.0 or 3.0. Device Manager also does not say what version.

I have to know, whether this thing is PCI Express 2.0 or 3.0.

I looked up the model and the processor on the C models is a J2900 - its bay trail based and supports a single pcie 2.0/x4 connector. I'm rather doubtful if this is the case, that you want to put a good gpu there.

HWiNFO has more reliable detection than CPUID.

For example, on my system CPUID wasn't able to detect PCI-E revision, but HWINFO was.

I tried this and I am pretty sure that your screenshot is showing the PCIe version of the device plugged into the slot rather then the capability of the slot itself. – Clifford – 2019-04-27T07:55:27.807

When I was young, I used a software called "everest" to check the hardwares and most of the time, it could tell me tons of information. Seems it is available through the cnet. If you really can't figure out, treat it as 2.0 may be a good choice.

Great. I found this software on CNET, I tried to downloaded, it started downloading strange other things I did not need, and my PC said there is a Trojan in there and it was quarantined. – Mark Galeck – 2015-02-01T06:02:14.473

CPUID is a pretty good tool that tells you a lot about your CPU/Motherboard/RAM. http://www.cpuid.com/softwares/cpu-z.html

You can run it without installing with the ZIP version.

Downvoted - CPUID is a great tool but it does not report PCIe revision. – Thomas – 2018-05-02T16:39:55.273
